A tactic I've been planning to use, but don't know if it actually works or
not, is to disable the button first thing in its onClick so the second click
occurs on a disabled button. Does anybody know if this actually works or
not?

If you are lucky and are feeding this form data to a database, you can
create a unique hash field from other fields that would not change from
click 1 to click 2. Then just make the database treat the hash as a unique
index and it should prevent double entries. Works for me.
Other advice is to not tell the double clicker that had an error; Just
silently ignore their second request.
